The authors investigated the safety of a monthly high-dose of vitamin D3 supplementation taken for up to 4 years, using data from a randomised trial of 5108 adults aged 50-84 years old from Auckland. They conclude from their analysis that "monthly supplementation of 100,000 IU vitamin D3 for a median of 3.3 years did not affect participant-reported adverse events".
